    By providing crucial geochemical support for Zambia's foundational geology, agricultural productivity, environmental conservation, mineral exploitation, and other domains, the Sino-Zambian Cooperation project has closed the country's national scale geochemical mapping gap. The overall abundance and geographical distribution of B and Se in Zambian stream sediments are the main objectives of this paper. The median concentrations of B and Se are 12.74 μg/g and 0.056 μg/g, respectively. The distribution patterns of B concentration appeared to be relatively uniform, lacking distinct indicators, whereas that of Se was more pronounced. In comparison to other tectonic belts, the Domes Region, Lufilian Arc and Choma-Kalomo Block have greater median and average concentrations of Se. Black shales and vast epithermal metallogenic zones are common in the Kawana-Solwezi-Ndola and the Mansa-Mporokoso-Kasama regions, which also have high Se contents. These regions could serve as promising places for the advancement of selenium-enriched agricultural practices.
